Xperia xz SIM not detected

[K755]

On my xperia xz when using a sim card and a micro SD card together the sim card is not detected by the phone, but the phone will detect the SD card. When I take the micro SD card out the phone will detect the sim card fine .Any suggestions?

First, if this is a new device, or still under warranty, I would contact the manufacturer about the issue.

However, if it isn't under warranty, then I would first look inside that area (the slots) and make sure nothing is bent incorrectly, debris inside there or missing any of the small metal parts. Any of these would cause that issue.
